Description

Application

• Non-targeted analysis and toxicity prediction for evaluation of photocatalytic membrane distillation removing organic contaminants from hypersaline oil and gas field-produced water.: The study uses 2-Butanone in experimental setups to assess the removal of hazardous organic compounds in water treatment processes, highlighting its role in environmental safety and sustainability (Delanka-Pedige et al., 2024).


• Lipid and volatile profiles of Finnish oat batches of pure cultivars: Effect of storage on the volatile formation.: This research utilizes 2-Butanone for the extraction and analysis of volatile compounds in oats, which helps in understanding the effects of storage conditions on food quality and safety (Puganen et al., 2024).
